Abstract (en)
[origin: WO2008151351A1] A method of forming an electrical connection between an electrode and an actuator in an inkjet nozzle assembly is provided. The method comprises the steps of: (a) providing a substrate having a layer of drive circuitry, the drive circuitry including the electrode for connection to the actuator; (b) forming a wall of insulating material over the electrode; (c) defining a via in the wall, the via revealing the electrode; (d) filling the via with a conductive material using electroless plating to provide a connector post; (e) forming at least part of the actuator over the connector post, thereby providing electrical connection between the actuator and the electrode.
